Active clinical trials for "Hypertension"

A majority of Korean doctors tend to add other antihypertensive rather than to titrate the same drug. However, we try to induce doctors to titrate the Sevikar than to add other antihypertensive if patients are not controlled with Sevikar 5/20mg(amlodipine 5mg + omlesartan 20mg). As above, for patients who are not controlled with Sevikar 5/20mg, doctors will proceed to other prescription pattern with other choices of titration to Sevikar 5/40, 10/40mg. It is important to evaluate BP lowering efficacy of Sevikar through the titration step in patients uncontrolled with Sevikar low dose. Thus, this study is designed to demonstrate the efficacy of Sevikar by titration in patients who are not controlled their BP with low dose of Sevikar.

A randomised crossover trial of anti-hypertensive medication dosing regimen in effective blood pressure control. To investigate whether there is a difference in 24 hour blood pressure (BP) control when antihypertensive medications are taken in the morning compared with the evening.

Investigators want investigate the following hypothesis: Nebivolol increases nitric oxide activity in the systemic circulation and the kidney The increased activity of nitric oxide during nebivolol treatment can be demonstrated by inhibition of NO synthesis with L-NMMA. We expect increased responses in blood pressure and sodium excretion is expected during nebivolol treatment compared to placebo.

This is a pilot study to assess the effectiveness, safety and feasibility of carotid body removal in patients with high blood pressure (hypertension) resistant to medical treatment. Patients with high blood pressure are at significant risk of medical complications including stroke and heart disease. The principle research question is whether removal of the carotid body will lead to an improvement in the blood pressure of this patient group.

This is a placebo-controlled, double-blind, parallel, randomized, two-part, dose-confirming clinical study characterizing the pharmacodynamic effects of pulsed iNO using the combination product, inhaled nitric oxide/INOpulse DS-C vs. placebo in subjects with World Health Organization (WHO) Group 3 pulmonary hypertension (PH) associated with Chronic Obstructive Pulmonary Disease (COPD) on Long Term Oxygen Therapy (LTOT).

This is a prospective, single-arm, non-randomized and open label feasibility study. The study is intended to evaluate safety and efficacy of multi-electrode radiofrequency renal denervation in patients with uncontrolled hypertension.

In participants with a diagnosis of open angle glaucoma (OAG) or ocular hypertension (OHT), the primary objective is to demonstrate that the mean IOP reduction after 3 months of treatment with BOL-303259-X once daily (QD) is non-inferior to timolol maleate 0.5% twice daily (BID). The secondary objective is to demonstrate the superiority of BOL-303259-X QD to timolol maleate 0.5% BID. This assessment will be performed if the non-inferiority of BOL-303259-X QD to timolol maleate 0.5% BID is determined. An open label safety phase will be conducted at the end of Visit 6 (3 months) where all participants will receive BOL-303259-X QD for an additional 3 months.

Left ventricle diastolic dysfunction (LVDD) is associated with resistant hypertension. In addition, brain natriuretic peptide (BNP) levels are elevated when LVDD is present. It has been shown that phosphodiesterase-5 (PDE5) inhibition improves left ventricle diastolic function in hypertensive rats, despite any difference in blood pressure levels. Also, left ventricle diastolic function enhancement reduces BNP concentration in hypertensive patients. However, it is unknown if these effects exists in humans with resistant hypertension. Therefore, this study was developed to evaluate if the use of a PDE5 inhibitor (tadalafil) for 2 weeks improves LVDD and its effects in BNP levels in resistant hypertensive patients.

The postpartum period represents a stage of the pregnancy-puerperal still rarely addressed scientifically. There are no reports in the literature and concrete enough to elucidate important issues, especially in the field of hypertension and pregnancy. Searches based on current evidence concentrate their focus on the diagnosis of hypertensive disorders and treatment of these diseases maternofetais repercussions. However, the prognosis in the short and long term, as the BP outcome in mothers with severe preeclampsia, the most effective treatment for the control of hypertensive crisis and metabolic and cardiovascular events after two years of termination of pregnancy require further clarification. The main idea for developing this research came from the clinical experience with the use of captopril in Obstetric ICU IMIP. This drug has long been used in postpartum women with severe preeclampsia or chronic hypertension exacerbated by pregnancy for control of hypertensive crisis and keeping pressure levels. Following the technical standards of the institution and during his administration, there were reports of side effects such as dry cough and nausea, beyond the threshold dose of 150mg daily captopril was easily achieved hindering control the use of hypotensive. Alternative therapy, clonidine began to be used in mothers with some restriction on the use of ACE inhibitors and its hypotensive effect for peak pressure was satisfactory. What is not known yet is how long clonidine reduces high blood pressure and how long to leave stabilized compared to the use of captopril. There are no reports in the literature databases, no randomized clinical trials that prove the effectiveness of clonidine for the treatment of hypotensive pressure peaks in this particular group of patients, even in comparison with other classes of antihypertensive drugs, especially captopril, to this purpose. The investigators' primary assumption is that clonidine has better effectiveness in decreasing the frequency of pressure peaks when compared with captopril.

To determine the efficacy of Azilsartan 20 mg versus Amlodipine 5 mg oral administration once per day for 8 weeks in patients with grade I or grade II essential hypertension.
